Strange bug. Game ended with everyone dying to someone else (my last plunder was WW, so I plundered him but he killed me). I had already plundered 2 players, died on the night of my third plunder, but game ended as a draw not a win for me. Yes, I died, but the wiki explicitly states that

"you don't need to be alive in order to win. If you successfully plunder 2 players before you die, you will still win at the end of the game, even if you died the same night you got your second plunder. "

More likely this is a visual glitch, or an error that happens when everyone is killed despite a Pirate winning the game solo, while dead.

The win screen in my previous gameplays fails to show up for the Pirate, when they have already gotten at least two plunders.I do not have screenshots, but I've had a lot of people talk about it.

Might be an issue conflicting with the wipe-out=draw over winners, though I don't know the code.

For instance, everyone dead while a Jester wins shows the Jester screen, which works fine, but there's a lot of talk about everyone dead despite a Pirate winning and the win screen does not appear for the Pirate, and instead shows as a draw.
